NEW  YORK,    March,  1904. 


The  great  increase  in  the  demand  for  instruments  and  tools  for 

FOREST  WORK 

has  induced  us  to  issue  this  special  catalogue.  We  have  had  the  privilege 
of  participating  in  the  developing  of  many  instruments  used  and  re- 
commended by  the  Bureau  of  Forestry  in  Washington,  and  take  this  occasion 
to  extend  our  thanks  to  the  several  forest  experts  who  have  aided  us  by  their 
advice  and  suggestions. 

It  is  our  aim  to  gain  and  maintain  for  this  line  the  same  high  reputation 
which  we  are  enjoying  since  many  years  for  our 

Drawing  Materials,  Surveying  Instruments,    Measuring  Tapes. 

These  are  described  in  our  General  .Catalogue  (500  pages),  which  we  send  free 
on  application. 

Those  of  the  articles  in  our  General  Catalogue  which  are  commonly 
used  also  for  forestry  work,  are  repeated  in  this  list  under  the  same  numbers 
which  they  bear  in  our  general  catalogue. 

We  hope  that  we  shall  succeed  in  meriting  the  patronage  of  those  who 
are  interested  in  the  articles  here  described. 

Very  respectfully,

THEE  CALIPERS. 


FOLDING  POCKET  CALIPERS, 

Patented  Feb.  18,  1902. 


No.  4300. 

The  Folding  Pocket  Calipers  are  of  the  style  of  the  K  &  E  Ivorine 
Pocket  Rules,  described  under  Nos.  1730-4  Ivorine,  etc.,  on  preceedino-  page. 
They  are  f  in.  wide  by  about  ^  in.  thick  and  have  stout  steel  springs  to  hold 
the  folds  in  alignment,  and  the  patent  metal  tips.  The  beam  of  this  caliper  i& 
also  a  handy  and  correct  48  in.  pocket  rule. 

One  side  of  the  8  fold  beam  is  blank  for  the  first  3  folds  and  the  other  5 
folds,  the  beam  of  the  caliper,  are  divided  to  inches  and  sixteenths.  The 
3  blank  folds  are  set  at  right  angle  to  the  balance  of  the  rule  and  are  there 
held  by  a  pivoted  nickelplated  brace,  as  shown  in  cut,  forming  the  fixed  arm 
The  sliding  arm  is  provided  with  a  nickelplated  spring  plate,  which,  when 
pressed  down  holds  the  arm  vertical  on  the  beam.  It  readily  passes  over 
the  joints  of  the  beam  on  releasing  the  pressure  on  the  springplate 

The  other  side  of  the  caliper  is  divided  over  the  entire  48  inches  into 
16ths,  to  serve  as  a  measuring  rule.

HYPSOMETERS.

No.  4400. 


4400.     Hypsometer  (after  Klaussner).     Brass,  graduated  surfaces 

silvered,  in  wooden  box,  8  X  2f  X  2f  inches each    |26  00 

This  Hypsometer  offers  the  advantage  over  most  others  that  the  total 
height  of  the  tree  or  other  object  can  be  read  direct  from  one  scale  and  that 
it  does  not  require  the  adding  of  the  readings  above  and  below  the  observer's 
level.  The  weighted  altitude-scale  is  much  steadier  in  the  wind  than  a  plumbbob. 

This  Hypsometer  consists  of  a  base  rule  (6  in.  long),  a  hinged  sighting 
rule  and  an  altitude-scale  held  vertical  by  a  weight.  The  base  rule  is  gradu- 
ated up  to  60  equal  parts,  each  part  divided  to  halves,  forming  the  distance 
scale.  It  carries  a  slide  with  reading  line,  to  which  the  weighted  altitude 
scale  is  attached.  The  altitude-scale  is  graduated  to  50  equal  parts,  each 
part  divided  to  halves.  The  graduations  may  be  read  as  yards,  meters, 
feet  or  in  any  other  unit,  depending  on  the  unit  adopted  in  measuring  the 
base  line  (object  to  observer).  The"  slide  of  the  altitude-scale  is  set  on  the 
distance  scale  to  correspond  to  the  measured  base  line.  The  sighting  rule  is 
hinged  to  the  near  end  of  the  base  rule,  and,  like  the  base  rule,  has  a  hair- 
line siajht  at  its  further  end.  At  the  joint  of  these  two  rules  is  a  revoluble 
peep  sight,  which  can  be  directed  to  either  of  the  two  hairlines  by  a  milled 
disk.  After  sighting  the  base  of  the  object  along  the  base  rule,  the  sighting 
rule  is  raised  by  means  of  a  high  pitch  thumbscrew,  until  its  hairline  cuts  the 
lop  of  the  object.  The  instrument  has  a  jointed  ferrule  with  clamp  screw 
threaded  to  fit  the  regular  photographer's  tripod  screw. 

4402.  Support  with  Gimlet,  for  attaching  to  a  tree  or  post,  hard 

wood  cross  piece " each  $  1  00 

4404.  Brass  Ferrule,  to  fit  the  support  with  Gimlet,  or  Jacob  Staff, 

or  tripod «  1  00 

For  Jacob  staff  and   Tripods  see  page  9. 


Tli  is  hypsometer  is  particularly  adapted  in  eases  where  necessity  of  haste  or  the 
roughness  of  country  make  the  use  of  a  tripod  impracticable.  The  resul-ts  obtained  are 
more  accurate  when  using  a  tripod  than  without  one.

4410.  Hypsometer  (after  Faustmann),  brass,  graduated  surface 

silvered,  hinged  mirror  mounted  in  aluminum,  folding 
sights,  folding  swiveling  handle.  In  cloth  covered 
pocket  with  cover  flap,  3|  X  7£  X  f  in.  With 

Directions each    $19  50 

This  mirror-reading  Hypsometer  is  3|  X  7  in.  It  is  provided  with  two 
scales  :  the  scale  of  heights  on  the  lower  edge  of  the  instrument  and  the 
scale  of  distances  on  the  two  edges  of  the  groove  in  which  the  slide  moves. 
The  slide  carries  the  plumbbob  cord  and  has  two  reading  lines  marked  I  and 
II,  corresponding  to  the  two  scales  of  distances,  also  marked  I  and  II.  It  is 
held  in  place  by  a  spring.  The  plumbbob  is  stored  in  a  small  tube  at  the  back 
of  the  frame.  The  peep-hole  and  hairline  sights  are  hinged  to  fold  down. 
The  hinged  mirror  is  5f  X  f  in.  The  cylindrical  nickel-plated  metal  handle 
on  the  reverse  side  of  the  instrument  swivels  and  also  folds  down.

In  No.  5703  the  reflector  is  a  narrow  prismoid,  crossing  the  middle  of  the  field  of 
view,  so  that  the  field  appears  on  both  sides  of  the  reflected  bubble,  as  shown  in  above 
diagram.  As  the  lower  surface  of  the  tube  is  flat  and  parallel  with  the  bubble,  this  hand- 
level  can  be  used  also  as  a  contact  level.

frame,  in  sewed  leather  case "       18  00 

The  K  cV  E  Pocket  Omnimeter  combines  a  compass,  clinometer,  hand  level,  plumb 
and  contact  level,  so  that  it  will  indicate  magnetic  bearing,  azimuth  angles,  altitudes, 
levels  and  slopes.  The  Omnimeter  with  folding  sights  will  indicate  aximuth  angles  in 
their  horizontal  plane. 

The  combination  is  arranged  in  a  rectangular  frame  of  aluminum  alloy,  5Kx2%xK 
in.  and  weighs  about  5  ounces.  The  frame  serves  also  as  fiduciary  edge. 

The  Compass  of  2  in.  diameter,  has  a  needle  with  agate  centre  and  stop.  It  is  grad- 
uated to  2  degrees,  numbered  in  quadrants  at  every  ten  degrees. 

The  Clinometer  of  2  in.  diameter,  is  of  the  pendulum  disc  pattern.  It  is  graduated 
to  2  degrees,  reading  to  90  degrees  in  either  direction  and  to  percentage  of  slope. 

The  prism  of  the  hand  level  is  attached  to  one  of  the  long  sides  and  its  bubble  is  on 
the  opposite  side  of  the  frame. 

The  bubbles,  are  as  sensitive  as  is  permissible  in  a  hand  level.

No.  6935£. 


6927.  Field  and  Marine  Glass,  japanned  and  covered  with 
morocco,  object  glass  24  lines,  8  lenses,  magnifying 
power  about  3f  times.  The  telescoping  bar  is  inde- 
pendent of  the  focusing  screw,  as  described  above. 
In  soft  leather  case,  witlT  handle each  $  15  75 

The  glass  No.  6927  represents  a  happy  compromise  between  the  magnifying  power 
and  the  size  of  the  field,  as  neither  of  these  factors  has  been  reduced  at  the  expense  of 
the  other.  This  makes  it  particularly  well  adapted  for  a  search  glass  and  for  general  use. 
The  focusing  screw  is  independent  of  the  telescoping  arrangement,  so  that  closing 
the  glass  and  drawing  the  tubes  out  will  not  disturb  the  focus  to  which  they  have  been 
adjusted  by  the  focusing  screw. 

6935.  Field  and  Marine  Glass,  japanned  and  covered  with

The  Liliput  Steel  Tape  is  warranted  to  be  of  the  same  grade,  workmanship 
and  accuracy  as  the  other  K  &>  E  Steel  Tapes.  It  is  made  very  compact  and  light  and 
is  therefore  suitable  and  convenient  for  the  pocket.  It  is  a  durable  tape  and  will  wear  well. 

The  Home  K  &  E  Steel  Tapes  are  intended  to  supersede  the  woven  tapes 
which  on  account  of  their  low  price  are  often  used  where  a  more  reliable  tape 
ought  to  be  employed.  They  are  of  best  quali1  y  steel  and  accurately  divided.  The  grad- 
uations and  figures  are  bright  while  the  ground  surface  is  nearly  black,  so  that  the 
measurements  are  easily  read.  The  neat  sewed  leather  case  is  convenient  to  use  and 
to  carry  in  the  pocket.

No.  1727. 

These  Rules  are  made  of  carefully  tempered  spring  steel,  f  in.  wide 
and  graduated  on  both  sides.  They  fold  up  smaller  than  any  other  rule,  so 
that  the  12  fold  three  foot  rule  is  only  |  in.  thick  X  3f  in.  long  when  folded. 

The  divisions  are  sharp  and  accurate  and  the  numbering  is  very 
distinct  on  dark  ground.  It  runs  in  opposite  directions  on  two  sides.  The 
aligning  springs  at  the  joints  hold  the  rule  in  a  rigid  straight  line  when  it  is 
opened  without  in  any  way  interfering  with  folding  it.
